Abstract
We report a rare case that showed aggravation of neurological symptoms due to expansion of the synovial cyst at C7/T1 after several month of trauma and present the consideration of proper prevention and management. A 64-year old male was admitted by right arm weakness(GIV+) after a pedestrian traffic accident. According to computed tomography(CT) scan and electromyography(EMG), a brachial plexus injury was diagnosed and he was treated conservatively. After 7 months, he was re-admitted by the left side weakness(GIV-) with severe pain and magnetic resonance image(MRI) revealed the expanded cystic lesion at C7/T1 level which compressed the cord from left side. After administration of steroid, surgical resection was performed via posterior approach and partial laminectomy. The dural expansion was observed after total removal of cyst which was diagnosed as a pathologist and symptoms were completely recovered. Because of its possibility of expansion of the synovial cyst and critical myelopathic symptoms can be induced in cervical spine, immobilization should be in consideration for acute period of post-trauma, especially, in old-aged patients with degenerative facet joints. And surgical procedure should not be delayed if symptoms developed.
